Laughter was not the best medicine for a woman who stuck a butter knife down her throat. In fact, it landed her in the emergency room.

The New England Journal of Medicine published X-ray images showing the knife lodged in the 30-year-old’s esophagus.

Drs. Aida Venado and Sarah Prebil said the woman had a history of bulimia, and stuck the knife down her throat to prove to her friends that she no longer had a gag reflex because of it.

Something made her laugh, and the knife slid down into her esophagus.
